LK-S49 PS Defoamer
Optimize Your Sealant and Coating Performance
Introducing LK-S49 PS Defoamer
LK-S49 PS Defoamer is a modified silicone fluid defoamer engineered to efficiently eliminate foam in pour grade polysulphide sealants and similar high-viscosity resin systems. This advanced formulation not only rapidly defoams but also prevents the formation of new foam, enhancing the spreading ability of the sealant.

Why Choose LK-S49 PS Defoamer?
Effective Foam Control:
Quickly defoams and prevents foam in high-viscosity systems.
Enhanced Spreadability and Levelling:
Improves the leveling and spreading of polysulphide compounds.
Versatile Use:
Suitable for oil/solvent-based systems, including paints and coatings.

Product Composition:
Formulation of foam-destroying polymers and polysiloxanes.

Applications:
Construction Industry:


Defoamer and Leveler for Pour Grade Polysulphide Sealant or Viscous Resin Systems –
Product LK-S49 PS Defoamer effectively eliminates foam and bubbles in polysulphide sealant and prevents new ones from forming, even at low dosages of 1-2%. It also enhances the spreading and leveling of polysulphide compounds and other viscous resin systems.
Coating Industry

Product LK-S49 PS Defoamer is highly effective both in the manufacturing process and during application as a defoamer and air release additive for solvent-borne and solvent-free coating systems. It is particularly recommended for use in highly viscous resin systems such as lacquer epoxy and polyurethane.
